If you need to modify header files
copy the header to the project directory and run the inctw script
provided. This will produce a hierachal set of directories which mimic
the library structure with a soft link to any header in your working directory
which is also found in the library.
Any modifications to this file will automatically get included in your compiled code.
Note however, modifications to structures will not apply to .o files
which have not been recompiled by your Makefile (ie: those still in the library).
